NAlLlNG-MACHINE FOR BOOTS AND SHOES.

SPECIFICATION forming part of Letters Patent No. 332,032, dated December 8, 1885.

' Application filed November 24, 1884. Serial No. 148,666. (No model.) I

To all whom it may concern.-

Be it known that I, EDWARD B. ALLEN, of Portland, county of Cumberland, State of Maine, have invented an Improvement in Heeling-Machines for Boots and-Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

This invention relates to that class of heeling-machine known in the market as the Mo- Kay & Bigelow, it being substantially represented in United States Patent No. 203,440, dated May 7,1878, and has for its object improvements in mechanism for automatically placing the top lift in position, and also to improvements in mechanism for controlling the movements of the nailing and of the trimming devices. In another application filed by me for United States Patent, Serial No. 130,242, I have shown and described a mechanism for automatically presenting a top lift in place, and the mechanism herein shown is intended as an improvement thereon. The same application, and also a second applition, Serial No. 130,341, shows and describes mechanism for automatically operating the top-lift plate, and it will be understood that in practice the machine herein described will be provided with a top-lift-.

plate-moving mechanism,substantially such as therein described. To avoid the delay occasioned in actuating these several treadles in their order by the operator, and to make the machine automatic in its operations from the time the heel is to be nailed to the shoe until the heel is trimmed and released, I have reorganized the said machine and provided it with mechanism under the control of but one treadle, one movement of which by the operator will engage a clutch to start the machine,

raise the die-bed spindle to clamp the heel against the shoe, and thereafter certain cams and devices under their control will keep the said clutch in engagement, and alsoeffect the engagement at the proper time of the clutch to start the trimming mechanism, and the top lift having been added, and the heel having been trimmed and its mechanism restored to its starting-point, the die-bed spindle will be automatically lowered and all the clutches disengaged.

Figure 1 is a left-hand side elevation of a machine of the class referred to embodying I lift; Fig. 2, an enlarged detail of part of the top-lift carrier. Fig. 3 is a section of Fig. 2 in the dotted line a" as. Fig. 4 is a right-hand side elevation of thelower part of the machine shown in Fig. 1. Fig. 5 is a vertical central section of Fig. 4. Fig. 6 is a horizontal section in the line 00 00 Fig. 5. Fig. 7 is a detail to be referred to; and Fig. 8, a detail of the track for moving the latch, to be described.

The frame-work of the machine, shaft a, driving-pulley b, shaft 6, having the crank or projection 2', gear (I thereon, the walking-beam n", rod p link 8', shaft 1?, cam-plate a link x, lever 3 the working screw-spindley, the diebed spindle Z, the toggle-lever 7c, the trimminglever a", the carriage '0", its guide-rail s, and the chain 0, sheaves n and p, lever f, knock-off cam w, the trimming-shaft 8, its crank 14, to move the lever a, the gear 7, loose on the shaft 8, the

in the patent referred to, wherein like letters are employed to indicate like parts, it being, however, noted that the rod 0 is shortened,and that some parts heretofore connected with it have been omitted, and it will also be observed that the devices for moving the walking-beam and operating the link 23 are somewhat al tered, as will be described.

The carriage D or jack employed in connec tion with the spindlef to hold and adjust the shoe B while the heel is nailed to it and while the heel is being trimmed, and the nail-driv-. ing mechanism H and heel-trimming mechanism H, both deriving their movement from the die-bed spindle Z and the lever a, respectively, are all substantially as in the wellknown McKay 8t Bigelow machine referred to, and hence need not be herein further described. The said devices are, however, referred to and described in the United States Patent No. 203,440. The nail-box A,which contains the usual nail drivers, and has at its top a pivoted top-lift plate, is the same as that referred to by like letter in my application Serial No. 130,241, the said nail-box and top-lift plate being also common to the United States Patent N 0. 166,795, dated August 17, 1875. The top-lift carrier (shown best in Fig. 2) is composed of a head, a made vertically adjustable in a block, b, adjustably attached by a setscrew, to an arm,- LP, of a slide-rod, e, preferablymade square or angular, to obviate rotation thereof, the said slide-rod having its bearings in guides fixed to the frame. The head is provided with levers or arms pivoted at g, the said arms having pivoted in turn upon them the top-lift clamps if, which are preferably serrated, as shown, and concaved to grasp the edges of the top lift, The clamps are normally kept pressed against the top lift by suitable springs, k preferably made adjustable byscrews m. The rear end of the top lift is acted upon by 'a-concaved dog,

, n pivoted upon a slide, o ,which,'when thedog is brought to a point to insure the proper position for the top lift with relation to the top-lift plate (not shown) at the top of the hailbox, is secured in place by the set'screw f. The slide-rod "e referred to, has a pin, 1", ex;

tended laterally from it which is embraced by the forked lower end of the lever '8 "pivoted at t, the said lever being vibrated by and" locking the connecting-lever a pivoted at its rear end to the rod 19, the lever s and rod e being moved forward to placea top lift in po sition when the spindle f is lifted, the'j'oi'ntf between the rod 19 and lever 8 being at sirch time broken or sprung, as in Fig. 1, wherein" the top-lift carrier is represented as moved forward to place 'a top lift in proper position to be blinded upon the projecting nails of i the attached heel when the 'diebe'd spindle is next raised.

it, carries the rod 6 back with it; but just before the plate strikes the said pin the end of the said plate also strikes the lower end of j the connecting-lever'u lifting it so that the upturned or angular end of the slot 0 therein is lifted from the pin (1 in the lever 5 thus" releasing the said lever, so that-it can be' carried bac-k with the rod (2 through the action of the pin 1". The lever a slotted and -co-op'- 1 crating with the pin a, forms'a locking device to retain the top-lift carrier forward. After the locki'ngdev'i-ce has been lifted, as stated, the pin '0 during the backward movement of the rod 6 is made to travel in the slot '0 and thereafter, when the rod p is moved back by the lever s in the direction of the arrow 1''0'0 thereon, Fig. 1, the lever u is drawn back, and its slotted part0 rides on the pin until-the bent or angular part of the'slot reaches I the said pin, when the lever 1& drops, and it and the lever 8 become again locked together,

so that'as the rod 0% is again moved in the and extended through an eye in the pin or bolt or, which connects the die-bed spindle with the toggle k, a spring, a placed on the said rod below the bolt a, being retained in place by the nuts a. a not of my invention, and is not herein claimed.

This connecting-rod is The leverf, connected with the pin whichjoins the u'pperand lower members of the toggle k,

is lifted into engagement with the crank '2', which 'straighten's thetoggle by a crank, d on a shaft, d, provided with a toothed gear, d

running loosely thereon, the said gear being engaged and driven by a pinion, d fast on the shaft 6. The gear d has its hub at its outer side provided with a tooth, d. The shaft d has fast on it,outside the gear d,an arm, d, provided with a pivoted dog, d acted upon by aspring-pressed pin, d", the latter acting to keep one end of the said "dog in contact with the tooth d", and at such time insure the rotationof the gear d in unison with the shaft d",

the said arm, dog, and tooth constituting a clutch, {the dog being held out from engagement with the tooth dZunt-il the machine is to be started, by 'means of the shoe 6, secured to an arm, '6 attached by set-screws'e to'a slidepin, 6, fitted into a fixed box, e;

When the treadle f is 'depress d lower side strikes the elbow-lever f pivoted at f*, and turns the latter, causing it toac't' against the lug f, forming part of the arm e thus moving the said arm outward or away from the side of the frame,removing the shoe '6, attached to the arm 6 from contact with" the end-of the dog (2", which results in enabling the pin "d placed in a guide 'on the armd and surrounded by a spring, (not shown,) to

turn the said dog and effect the engagement of its; opposite end with the toothdof the hub of the gear 'd, which will cause the rota tion of the shaft d 'w ith the said gear d, the crank (1 of the shaft 01* lifting the lever into position to be struck by the crank ion t e r0 tating shaft 12, the said lever, when moved h y' 25 the crank 'i, straightening the toggle and lift P ing the "d ie-bed spindle to drive the nails which attach the heel to the shoe, such movement.

being accomplished through a partial rotatioh of the gear d. The n-ailshavi'ng beendri'ven,

"cam 00, as herein shown, is mounted on a stud,

crank d, in the continued rotation of the gear (1", again strikes the lever f and lifts it until the crank i again strikes the shoulder 80 thereof and straightens the toggle and lifts the diebed spindle. The shaft (1* has fast upon it within the frame a pinion, which engages a cam-gear, g mounted on a stud, connected by a set-screw (see Fig. 6) with a sleevelike part of the fixed box e The cam-gear g, twice the diameter of the pinion g, has at its outer side a cam, h, (see Fig. 7 which at the proper'time acts upon the roller or other suitable end, h, of the slide-rod c, referred to, the said cam acting on the said slide-rod serving to retain the shoe 6 in position to maintain the engagement of the dog d with the tooth d and continue the rotation of the shaft (1 until the cam-gear g has completed a rotation; This cam-gear has at its inner side, nearest the center of the frame, a cam, h, which at the proper time strikes the rod h, carried by arms h on the rod b the latter being jointed by link h to the lower end of the lever 23, the latter, when moved through.

themedium of the said cam, actuating the shoe 7) in the direction to effect the engagement of the dog 11 with the ratchet 9, to start the shaft 8 and its crank 14 and cause the vibration of the lever a which operates the heelt-rimmingmechanism in the usual manner. The rod h is kept pressed toward the gear by the spring is, and as soon as the cam it passes beyond the roll h the lever 23 is moved by the spring is back into its normal position, thus placing the shoe 1) in position to strike the dog 11 to effect its release from the ratchet 9 when the rotation of the shaft 8 is stopped, as usual. Just after the usual knife of the heel-trimming mechanism has completed its work a pin or projection, k strikes the upper end of the lever It, pivoted at 70 and moves the latter, so that its lower end, then in'contact with the pin 75 of thelever f, it be- Y ing understood that the toggleis yet straight,

moves the said lever f to effect the breaking or springing of the toggle k, which springing was previously accomplished by the cam :0. Immediately after starting the shaft 8, as described, the cam h of the gear 9 passes beyond the roll k and permits the slide-rod e and its arm and shoe 6* to be moved by the spring 6 to place the shoe in its normal position and insure the disengagement of the dog d from the tooth d and stop the shaft d", the lever f during such movement, acting to lift the treadle.

I do not desire to limit my invention to the exact devices shown between the cam-gear g and the shoe 11 to effect the movement of the latter, nor to the exact devices shown to effect from the said cam-gear that movement of the shoe 6* which maintains the engagement of the;dog d with the tooth d for more than one full rotation of the shaft d, and then permits the movement of the said shoe to effect the disengagement of the dog (1 from the said tooth d, for it will be understood that other equivalent devices might be employed. The shaft 6, its attached gear d, pinion d gear d and the gear 7, loose on the shaft 8, and driven from the shaft a, as is also the gear d, are rotated continuously, and these gears, through the dogs and shoes described, are caused to operate the shaft (1 and the shaft 8 at the proper times to effect the operation of the die-bed spindle and trimming mechanism in the necessary order, and it will be noticed that the movements of all the parts, to attach a heel to aboot or shoe, apply the top lift, and then trim the heel, are all effected by one single treadle.

The frame-work of the machine is designated WV.
